Valvular Diseases Flashcards
what is S3?
heard 0.1s after second heart sound, rapid ventricular filling chordae tendinae
S4?
ALWAYS ABNORMAL, STIFF HYPERTROPHIC VENTRICLE. turbulent flow le lub dub
erbs point?
3rd intercostal space left sternal border, heart sounds
special manoeuvre to hear mitral stenosis?
turn on left hand side
special manoeuvre to hear aortic regurgitation?
sit up, lean forward breath out and hold
which murmur goes towards carotids?
aortic stenosis
which murmur goes towards left axilla?
mitral regurgitation
in stenosis what do you get?
hypertrophy of chamber
when you get regurgitation the chamber becomes?
dilated
mitral stenosis is caused by?
infective endocarditis, rheumatic heart disease
mitral stenosis type?
mid diastolic low pitched rumbling. loud lub then dub durrr
palpate a tapping apex beat loud S1
malar flush- due to back pressure rise in CO2 and vasodilation
associated with atrial fibrillation
mitral regurgitation?
incompetent mitral valve
pan systolic murmur
high pitched whistling BURRRR
radiates to left axilla
associated with congestive heart failure, reduced ejection fraction, backlog blood
might hear 3rd heart sound
causes of MR?
idiopathic with age
ischaemic heart disease
infective endocarditis
rheumatic heart disease
connective tissue disorders
aortic stenosis?
ejection systolic murmur, high pitched, crescendo-decrescendo
radiates to carotids
slow rising pulse
narrow pulse pressure
exertional syncope
aortic stenosis?
chest pian, sob, syncope
ejection systolic murmur, high pitched, crescendo-decrescendo. thrill
radiates to carotids
slow rising pulse
narrow pulse pressure
exertional syncope
soft/absent s2
s4
decreases following valsalva manoeuvre
cause of AS?
idipathic age calcification
rheumatic disease
bicuspid aortic valve
williams syndrome- supravalvular
HOCM
aortic regurgitation?
aortic valve incompetent
early diastolic soft murmur
corrigans pulse/collapsing
rapidly appears then disappears
results in heart failure/ pulmonary oedema
austin flint- heart at apex
wide pulse pressure
aortic regurgitation causes?
idiopathic age related weakness
connective tissue disorders
grading murmurs?
Grade I: Difficult to hear
Grade II: Quiet
Grade III: Easy to hear
Grade IV: Easy to hear with a palpable thrill
Grade V: Audible with stethoscope barely touching the chest
Grade VI: Audible with stethoscope off the chest
what is an austin flint murmur?
This is heard at the apex as a diastolic “rumbling” murmur. This is caused by blood flowing back through the aortic valve and over the mitral valve, causing it to vibrate.
water hammer pulse?
quickly appearing then rapidly disappearing- radial artery
tricuspid regurgitation?
pan-systolic murmur. There is a split second heart sound due to the pulmonary valve closing earlier than the aortic valve, as the right ventricle empties faster than the left ventricle.
Thrill in the tricuspid area on palpation
Raised JVP with giant C-V waves (Lancisi’s sign)
Pulsatile liver (due to regurgitation into the venous system)
Peripheral oedema
Ascites
when is lancisi’s sign seen?
tricuspid regurgitation
causes of tricuspid regurgitation?
Pressure due to left-sided heart failure or pulmonary hypertension (“functional”)
Infective endocarditis
Rheumatic heart disease
Carcinoid syndrome
Ebstein’s anomaly
Connective tissue disorders, such as Marfan syndrome
